Abstract: A METHOD OF MAKING AN IMPROVED       INSTANT COFFEE           Richard Gregg, James A. Weikel, Jayantilal M. Patel, and Richard F. Durchholz Abstract of the Invention An improved instant coffee is prepared by subjecting roast and finely ground coffee particles of 5-800 microns to devolatilization and extraction operations under conditions which sustain the freshness of a desirable coffee volatiles and soluble solids.  A semi-bed of mechanically fluidized roasted and ground coffee particles is sprayed with 32°-110°F water and contacted with steam for devolatilization under an absolute pressure of 5-100 mm of Hg and a temperature of 32°-110°F.  The resulting volatiles-laden steam is then condensed under an absolute pressure of about 4-80 mm of Hg and under supercooling conditions to provide a frost. A coffee volatiles-containing concentrate is made from that frost by contacting it with an aqueous coffee extract.  Valuable coffee solids remain-ing in the devolatilized roast and fine ground coffee parti-ales are extracted therefrom by a slurry extraction operation.          Gentle agitation is employed to negotiate the extraction of soluble coffee solids without the release and emulsification of bitter coffee oils.  The extract is separated from slurry insolubles.  This extract and the coffee-volatiles concentrate provide the components of an improved instant coffee.

Abstract: PROCESS FOR THE JOINT COMBUSTION OF OFF-GASES AND          LIQUID RESIDUES CONTAINING CHLORINATED HYDROCARBONS.    ABSTRACT OF THE DISCLOSURE:  Off-gases and liquid residues containing chlorinated hydrocarbons, are subjected to joint combustion by for-ming a mist comprising a mixture of off-gases and ato-mised liquid residues, the latter being atomised by means of air and/or steam, and directing this mist into a pre-heated combustion chamber lined with refractory bricks. The mixture is introduced into the combustion chamber Jointly with combustion air through a burner having four feed pipes arranged coaxially with respect to each other and terminating in conically tapered outlets, the three outer feed pipes defining three separate and co-axial annular zones around the innermost feed pipe. The liquid residue fed in and burnt is used in a quantity sufficient to maintain in the combustion chamber a pre-determined maximum temperature which is not above the range 1200 to 1800°C, and which is compatible with the refractory properties of the brick lining of the com-bustion chamber. The resulting hot combustion gases are withdrawn from the combustion chamber, quenched with water, and hydrochloric acid is recovered from the re-sulting aqueous solution.

Selected subsections are selectively removed from the carrier sheet and aligned upon a receiving fabric surface where the indicia directly engage and become permanently bonded to the fabric surface in response to heat.  The carrier subsections are selectively removed from the fabric receiving surface following the application of heat and curing leaving the indicia permanently bonded to the fabric surface in predetermined alignment and spacing with adjacent indicia.  Aligned subsections may be interconnected through the use of an adhesive tape prior to the application of heat.

Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a circuit arrangement for generating stepping pulses for driving a stepping motor.  The circuit arrangement generates stepping pulses by means of which, unlike prior art arrangements, a movement of the stepping motor in the optimum load angle range can be achieved.  The stepping pulses are formed by means of several start pulses in short succession and a plurality of control pulses which are emitted whenever the rotor of the stepping motor has rotated by one stepping angle. In this fashion the stepping motor is accelerated by the maximum dynamic torque.  The stepping pulses are produced by means of a read-only memory (coefficient store), wherein data items coordinated with a particular characteristic have been stored.  The data items determine the division ratio of a frequency divider which produces the stepping pulses from timing pulses of a predetermined repetition frequency.

The data processor includes an arithmetic and logic unit for performing computational and decisional processes in a sequence determined by a program to count events in response to the detector signals, and to classify and accumulate the counts as data in separate locations  in semi-conductor memory for separate real time periods.  The portable reader instrument has a visual display device, a recording device, and a manually operable keyboard and switches for generating displaying commands and read commands and for transmitting those commands to the recorder unit for reading and displaying data as derived by the data processor of the recorder unit, without interruption of the recording mode, and to display on the visual display and re-record data received from the recorder unit in the recording device of the reader instrument.  The reader instrument is employed both for monitoring the operation of the recorder unit and for collecting data recorded in the semi-conductor memory of the recorder unit.

Abstract: ABSTRACT OF THE DISCLOSURE        A surgical microscope apparatus for use while suturing an incis-ion in the cornea for configuring the cornea to a spherical surface having a radius of curvature of a predetermined magnitude is disclosed. The micro-scope system includes a light source for projecting an image onto the cornea and prisms for optically splitting the image on the cornea into a plurality of images within the surgical field of view for viewing through the binocular eyepieces. The optical system can be adjusted to orient the images into a predetermined alignment and configuration indicative of the radius of cur-vature, the alignment and configuration occurring when the cornea sutures are tensioned correctly to indicate a spherical surface of the predetermined radius of curvature. The prisms are so-positioned to permit a portion of the surgical field of view to pass through the microscope undeviated to enable the surgeon to utilize the necessary suturing tools without multiple images of the tools. In a first embodiment a fixed location prism array is utilized for optically splitting the image and the optical system is adjusted by varying the magnification powers of the microscope. In a second embodiment, rotary prisms are in a fixed position within the optical path for optically splitting the image and the optical system is adjusted by varying the prism power.

The central processing unit communicates with the peripheral modules only through network message controllers which operate on a store and forward basis.          The network modules, central processing unit, control signal links and network links are duplicated and the central processing units connect to the control signal links through central message controllers which are also duplicated and each of which can - i -operate with either of the central processing units.  Under high load conditions, the origination of low-priority messages to central processing is inhibited by the central message controllers by substituting a special repeated code signal instead of the normal repeated code transmitted to indicate an idle condition, causing the network message controllers to do likewise, so that the peripheral modules can respond by in-hibiting, for example, the recognition of new calls for service.                             - ii -
